JS模拟Alert与Confirm对话框
这2个例子都是用原生JS写的,主要是用JS拼接了界面,并未做过多的事件监听。,样式用了Css3的一些特性。
调用方式则为:
//Alert Alert.show('我警告你哦~'); //Confirm Confirm.show('我是确认对话框',function(){ doSomething(); });
组件详情看下面的具体代码:
1.CSS样式
由于这2个组件的样式差不多,所用共用了一样的css,样式代码如下:
/** * dialog */ .dialog { top:40%; left:40%; width: 250px; min-height: 100px; position:fixed; z-index:9999; text-align: center; padding:10px; border:solid #bcc5c1 1px; background:#FFF; border-radius:3px; -moz-border-radius:3px; -webkit-border-radius:3px; padding:0px; behavior: url(PIE.htc); } .dialog .dialog-header { position:relative; width:100%; height:30px; margin:0px; background:#0CF; background:linear-gradient(top,#d1d4d3 0%,#c4c7c8 100%); background:-webkit-linear-gradient(top,#d1d4d3 0%,#c4c7c8 100%); background:-moz-linear-gradient(top,#d1d4d3 0%,#c4c7c8 100%); border-radius:3px 3px 0px 0px; -moz-border-radius:3px 3px 0px 0px; -webkit-border-radius:3px 3px 0px 0px; behavior: url(PIE.htc); } .dialog-header .header-left { width: auto; height:auto; float:left; margin:7px; } .dialog-header .header-right { width: auto; height:auto; float:right; margin:7px; } .dialog .dialog-content { font-size:14px; height:100%; width:96%; float:left; font-family:"Helvetica Neue", Helvetica, Arial, sans-serif; color:#424242; padding:5px; } .dialog-content .content-main { width: 100%; min-height: 40px; line-height:25px; float:left; white-space: normal; } .dialog-content .content-btn { float:left; width:100%; height:28px; margin-top:10px; } .btn { font-family:Arial, Helvetica, sans-serif; font-size:12px; text-align:center; vertical-align:middle; margin-right:5px; padding:5px 20px 5px 20px; text-decoration:none; border:#c4c7c8 solid 1px; border-radius:3px; background:#d1d4d3; background:linear-gradient(top,#d1d4d3 0%,#c4c7c8 100%); background:-webkit-linear-gradient(top,#d1d4d3 0%,#c4c7c8 100%); background:-moz-linear-gradient(top,#d1d4d3 0%,#c4c7c8 100%); color:#111c24; } .btn:hover { background:#d1d4d3; background:linear-gradient(top,#c4c7c8 0%,#d1d4d3 100%); background:-webkit-linear-gradient(top,#c4c7c8 0%,#d1d4d3 100%); background:-moz-linear-gradient(top,#c4c7c8 0%,#d1d4d3 100%); color:#111c24; } .alert-content { text-align: left; text-indent: 20px; } .alert { margin-left:140px; }
2.Alert
Alert 主要是模拟了界面,并显示提示信息。JS代码.Demo 可查看:http://wewoor.github.io/CNUI/document.html 。
//Alert var Alert = { func : function(){}, name : "dialog", show : function(msg){ //show function var confirm = document.createElement("div"); confirm.className = this.name; confirm.id = this.name;; var confirmHeader = document.createElement("div"); confirmHeader.className = "dialog-header"; var headerSpan = document.createElement("span"); headerSpan.className = "dialog-title"; var confirmContent = document.createElement("div"); confirmContent.className = "dialog-content"; var contentSpan = document.createElement("span"); contentSpan.className = "content-main alert-content"; var contentBtnDiv = document.createElement("div"); contentBtnDiv.className="content-btn"; var btnConfirm = document.createElement("a"); //确认按钮 btnConfirm.href = "javascript:Alert.hide()"; btnConfirm.className = "btn alert"; //按钮添加 contentBtnDiv.appendChild(btnConfirm); confirmContent.appendChild(contentSpan); confirmContent.appendChild(contentBtnDiv); confirmHeader.appendChild(headerSpan); confirm.appendChild(confirmHeader); confirm.appendChild(confirmContent); //default button headerSpan.innerHTML = "警示框!"; btnConfirm.innerHTML = "确认"; contentSpan.innerHTML = "这是一个警示框!"; if(msg != null && msg != undefined){ contentSpan.innerHTML = msg; } document.body.appendChild(confirm); return confirm; }, hide : function(){ var confirm = document.getElementById(this.name); if(confirm != null && confirm != undefined){ document.body.removeChild(confirm); } } }
3.Confirm 组件
confirm对话框并没有像原生的confirm组件返回true 或者false,而是点击确认按钮后执行了传入的回调函数,点击取消按钮则移除了这个组件。demo请看:http://wewoor.github.io/CNUI/document.html
//Confirm var Confirm = { func : function(){}, name : "dialog", show : function(msg,call){ //show function var confirm = document.createElement("div"); confirm.className = this.name; confirm.id = this.name;; var confirmHeader = document.createElement("div"); confirmHeader.className = "dialog-header"; var headerSpan = document.createElement("span"); headerSpan.className = "dialog-title"; var confirmContent = document.createElement("div"); confirmContent.className = "dialog-content"; var contentSpan = document.createElement("span"); contentSpan.className = "content-main"; var contentBtnDiv = document.createElement("div"); contentBtnDiv.className="content-btn"; var btnConfirm = document.createElement("a"); //确认按钮 btnConfirm.href = "javascript:Confirm.callback()"; btnConfirm.className = "btn"; var btnCancle = document.createElement("a"); //取消按钮 btnCancle.className = "btn"; btnCancle.href = "javascript:Confirm.hide()"; //按钮添加 contentBtnDiv.appendChild(btnConfirm); contentBtnDiv.appendChild(btnCancle); confirmContent.appendChild(contentSpan); confirmContent.appendChild(contentBtnDiv); confirmHeader.appendChild(headerSpan); confirm.appendChild(confirmHeader); confirm.appendChild(confirmContent); //default style headerSpan.innerHTML = "对话框"; contentSpan.innerHTML = "这是确认对话框?"; btnConfirm.innerHTML = "确认"; btnCancle.innerHTML = "取消"; //if the property html is not null and not undefined //just set this property. if(msg != undefined){ contentSpan.innerHTML = msg; } //set callback if(call != null && call != undefined){ if(typeof(call) == "function"){ this.func = call; } } document.body.appendChild(confirm); return confirm; }, hide : function(){ var confirm = document.getElementById(this.name); if(confirm != null && confirm != undefined){ document.body.removeChild(confirm); } }, callback : function(){ //执行call回调方法 this.func(); //隐藏confirm对象 this.hide(); } }
